EVALUATION OF FACTORS AFFECTING THE TENSILE PROPERTIES OF CEMENT-TREATED MATERIALS

THIS STUDY WAS PERFORMED TO EVALUATE THE FACTORS AND INTERACTIONS AFFECTING THE TENSILE PROPERTIES OF CEMENT-TREATED MATERIALS. NINE FACTORS WERE INVESTIGATED: CEMENT CONTENT, MOLDING WATER CONTENT, AGGREGATE GRADATION, CURING TIME, CURING TEMPERATURE, TYPE OF AGGREGATE, TYPE OF CURING, TYPE OF COMPACTION, AND COMPACTIVE EFFORT. THE FIRST FIVE WERE INVESTIGATED AT THREE LEVELS AND THE LAST FOUR AT TWO LEVELS. A STATISTICALLY DESIGNED FRACTIONAL FACTORIAL EXPERIMENT WAS RUN FOR THE EVALUATION. THE PARAMETER CONSIDERED AS A PRIMARY INDICATOR OF THE TENSILE PROPERTIES OF CEMENT-TREATED MATERIALS WAS INDIRECT TENSILE STRENGTH. ANALYSIS OF VARIANCE WAS USED TO DETERMINE THE SIGNIFICANCE FOR ALL THE MAIN FACTORS, TWO-FACTOR INTERACTIONS, AND THREE-FACTOR INTERACTIONS. THE HIGHLY SIGNIFICANT EFFECTS ARE DISCUSSED IN THIS REPORT, AND TABLES OF FACTORS AND INTERACTIONS SIGNIFICANT AT ALPHA LEVELS OF 1 AND 5 PERCENT ARE SHOWN. AS A RESULT OF THE REGRESSION ANALYSIS, AN EQUATION WHICH PREDICTS VALUES OF THE INDIRECT TENSILE STRENGTH WITHIN THE INFERENCE SPACE DEFINED BY THE EXPERIMENT WAS DEVELOPED. /AUTHOR/
